CARBURETER.

'To allwwm it may concern:

.State o f Indiana, have invented certain new yand useful Improvements in Carbureters;

and I do declare the following to be a.. full, clear, and exact description or the invention, reference being had to the accompanying drawings, and to the letters and figures 'of marked thereon, which form a part of this specification.

This invention relates to carbureters that are used in connection with explosive enafines andespecially such as are designed it; por use on automobiles, the invention hav ing reference particularly to the apparatus A C-C in Fig. l; Fig. 5,

'further object being to for admitting and controlling air to be carbureted, and- A to apparatus forfeeding the gasolene or similar hydro-carbon wlierewith to produce the explosive mixture for' the engines. y l

Objects of the .invention are to provide -above nien-` tioned character, which may be produced at reasonable expense, and adapted to be Voperated reliably, arid with the highest etilciency under various conditions required,

and be durable and economical in use; a provide an improved carbureter that will be adapted to be readily connected with engines at any required angle so as to be convenient in operation- With the above mentioned and other objects in view, the invention consists in acar bureter having novel featuresof construction generally and particularly with respect to the carbureting tube the carbureter including an improved combined admission.

and regulating valve for the air; and the invention consists further in. lthe parts and combinations and arrangements of parts, as

hereinafter :particularly described and defined in the accompanying claims.-

Similar reference characters in the va- 'irious figures of the drawings indicate like elements or features of construction rel ferred to herein.

A practical embodiment of the invention comprises reservoir 1 having a valve body 2 formed at the bottom thereof in which lis a valve seat 3, the valve body being provided with ar'couplingnut 4L connecting-a feed adapted to be connected to any source of supply whereby to supply the reservoir as' the like. lA feed needed with gasolene or I valve 6 is arranged in the valve bodyv to operate in connection with the valve seat 3 and it is provided vwith a valve stein T that extends up through the/reservoir, the latter being provided with a c ver 8 in which is an aperture 9 through whichv the valve stem extends loosely, the stem bein guided in the aperture in which there is su cieiit'space to permit air to pass through. Y

The top of the valve stem' is provided with.

a knob l0 for manually operating the valve G, but normally in operation the valve may be controlled by a float l1 preferably composed of cork and suitably secured to the valvestem S, preferably by means of a cpllar 12 secured to the float andpiovided with a set screw l13 engaging the valvel stem'.

open by force of gravity, and when sufficient liquid iassesintothe reservoir to, raise the float it will close the'valve. The reservoir has a projection lllon the exterior thereof that is preferably cast. integrally and con-l the pipe 5 being' T `When the reservoir. is empty the valve will nec-ts the wall of a carbureting tube l5 with 'the wall of the. reservoir, the 'carbureting tube being preferably cast integrally with the projection. tends horizontally with respect to the verti# cal reservoir and has an enlarged open end forming a. regulator valve case 16 tliathas an external flange 17 and preferably an in'- ternal flange. li'fon its end. vAn annular plate 1S is secured to the flange 17 remov ably by screw-bolts 19, the platevextending inward beyond the inner edge of the flange 17 and forming a valve-seat 187 at lthe inner, .side thereof. A guide-bar 20'fis sup- The carbureting tube. ex-` vor both nuts- QT,

ported .by the plate 18, being preferably formed integrally therewith, and it has a guide opening Q0 therein. rIhe plate 18 supports also a yoke Q1 which is preferably formed integrally with the plate and extends over the guide opening` 20 at a suitable. distance outivardly therefrom. A guide-rod Q9 is screwed into the yoke 21 and extends through the guide opening 20 into the bowl, and it has a lock-nut 23 thereon normally engagii'ig the front or outer side ot thel yoke. A sleeve QJ- is provided and arranged movably on the guide-rod 22, so as to move in the guide opening` Q0, the sleeve being a helder vfor a valve which -is designed to admit 'air into the carbureting tube and to regulate theadmission of the air. The valve comprises a disk Q5 which is mounted on the sleeve and has a suitable numherof aper-I tures 2G therein, the disk being` seated against a nut 2T that is screwed onto the sleeve, the"valve comprising also a companion disk'QS having apertures 29 therein registering With the apertures 2G. the'disk QSbeing placedbn the sleeve against thev disk Q5 and secured thereto by a' nut 2T screwed on tothe sleeve 2l, so that either 2" may be readjusted, in order that the valve disks may be readjusted along `the sleeve and also when either1 nut is slackened either disk may be readjusted rotatively, .so as to partially close the apertures therein more or less as may be desired. rI'he inner end of the guide-rod 2'2 has a plate 30 connecte-d thereto preferably so as to rotate thereon, and a'coil-spring` 31 is seated againf-ty the plate 30 and also against the disk 2S, so as to normally hold the disk against the seat 1S', and the tension oi" the spring may be varied by adjusting the guide-rod 22 in the. yoke 21. The plate 18 may be detached from the llange 17 in order to have access to the valve disks for readjusting them, although they may not require readjustment after having once been suitably adjusted .to adapt the rvalve for the services required. c

A valve-seat 32 is formed in the Wall Aot the. carbureting tube 15 near the. valve ease 16and ispro'vided With a regulating valve .B3/that is mounted in a valve body 3ft preierably formed integrally with the Wall of the carbureting tube, the valve having an operating stem/35 screwed into the valve body, the latter being provided ivith a packing-nut 3G and connected by a duet 3T with the reservoir 1. The valve body S-lf has a branch '38 that is in alinem'ent with the duet 3T and normally closed by a cap 39, and when the cap is removed the duct may be readily cleared of any obstructions vthat may form therein; and by removing the valve stem the passage from the duct to the carbureting` tubemay be readily cleared of obstructions.

The carbureting tube is provided with a A regulator that preferably comprises. a .rotativ'e shait't l() that is umuntedghin tlie\vall o'tf` lthe carburetiug tube, the wall being provided with a packing-lionel .on the.- ex-` terior thereof through ivhich the shat't efvtends, there being a packing-nut t2 on the padding-box, so that the shaft may be packed ior producing friction sullicient to hold the .shattagainst turning when the apparatus is operating. the shaft being provided `with an operating handle 43 on its outer end, and a disk il is secured to the shaft by a setscreu' l5 or otherwise Within the'ciirl'iiiret ing tube, so that the passageivay'in the earbureting tube maybe partiallyclosed-- more or less as may `be desiredorrequired vto supply the explosive enginefvvith 'carbu-1 reted air or vapor. l f

ln order to conveni ently' set the apparatus,- the carbureting tube 15 has a ilange 4G thatVJ is arranged at an oblique-angle therettf` and an end piece *i7 has a similar oblique'-` anglc flange At8 engaging 'the tlanged, a

coupling-nut -l9 connecting the t-Wo flanges together adjustably, t ie end 4T having sereiv lhreads 5() by which it maybe connected to the. connecting pipe or directly to the explosive chamber or cylinder of the engine.

ln practical use the earburetin' lifuid.

will be conducted from the main supply tank through the pipe .and be l'ed automatically into the reservoir 1 by means of the valve (5 and the float 11, and in case the valve (l sticks and tails to open 4at iirst it may be opened by manipulation of the knob 10..by hand, and when desired the valve may be held in closed position by means of the knob and the valve stem.
